Add email notifications when posts get a reply

Is there a way we can get an email notification when our posts get a reply from anyone that changes the record? Similar to Share Point where you can select and item and set up an email notification when any changes occurs to the post???
Getting an email on my inbox would tell me to go look at the post otherwise I have no idea if it has been looked at or if thee is a reply.

Thanks.

Sorry folks just remember the profile, so I went to my profile and found a place to setup email notifications, hope I get them. Thanks, problem solved. !!!
